DF****3(A) Inline Neutron Activation Coal Analyzer is of modular structure, which can be installed around the belt without the need to cut of the belt. When DF****3(A) runs, the belt will slide on the inner bracket of the measuring unit and all the materials passing through it will be tested, with no contact with such materials during the whole testing process, thus it has no influence on belt running. DF****3(A) can present the testing results every one minute, thus accurately analyzing the content of each element as well as relevant industrial indexes. It carries effective supervision and control on coal quality, with such features as no need to take samples, full material analysis, high analysis accuracy, etc., which has efficaciously solved such problems as lagging coal testing data, etc. By analyzing real-time detection information, it can conduct effective control on the production process, improve production technology, reduce production costs and raise product quality.
Principle:
DF****3(A) adopts prompt gamma neutron activation analysis (PGNAA) technology. After the nucleus captures the neutrons, it will be in the excitation status. Upon de-excitation, characteristic gamma rays corresponding to the nuclide will be emitted. By analyzing the gamma energy spectrum, the composition content of the materials under measurement can be got.

Technical parameters:
1.Measurement parameters: ash content, moisture, sulfur content, SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O, K2O, etc.
2.Calculation parameter: calorific value and any possible parameters that can use empirical equation.

Product application:
1.Classification & Piling
DF****3 (A) system can be used jointly with the process control software, so as to classify the materials, sort the coals with higher calorific capacity to the maximum and improve the effective utilization of various resources in the mine area.
2.Coal blending
DF****3(A) can be used jointly with the automatic batching software to carry out the coal material blending control in such industrial enterprises as coal mines, coal washeries, power plants, etc. Weighing instrument and analyzer can send current detection results into the batching software, and the latter then controls the feeding amount of each raw material feeder according to the target values of quality control parameters (calorific value, sulfur content and ash content) as set up by the users, so as to make the batching satisfy the quality control requirements. The batching software can also adopt manual mode. The feeding amount of each coal source can be controlled through the intercommunication system, thus guiding coal blending.
